BED-SPRING FABiRIC.

To all whom it may concern.'

Be it known that l, HENRY F. HAGER, a

citizen of the United States, and resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed- Spring Fabiics, of which the following is a specification` My present invention relates to bed spring fabrics in general and more particularly to the type of fabric commonly termed square or rectangulai"7 link fabric.

The invention hasfor one, of its objects the provision of a fabric of the character described, the links of which may be economically constructed -and assembled.

The cost of bed spring fabrics is estimated by the trade roughly from the- Vnumber of pounds of wire needed to form the individual and complete fabric and it is an object of this invention to provide a fabric which will require in its formation a minimum weight of wire consistent with the production of an efficient and durable fabric.

A further object of my invention Ais to" provide a fabric which will not lessen in Width materially when weight is sustained by the spring.

A further object of the invention is to provide a fabric of the character described, the links of which will not rattle or make other noise when the fabric is in use or when lit is being, handled in selling.

A still further object of the invention is lthe provision of a fabric which may be secured in a bed spring frame by a variable number of helical springs of the type ordinai-ily provided for this purpose without altering the number of longitudinal rows of links and without altering appreciabh7 the form of these links.

Other objects andadvantages of the invention will be apparent as the invention is better understood. from the following description when considered in connection Specification of Letters Patent.

Applcationled April 27, 1914. Serial No. 834,639.

Fig. l and-showing a' somewhat modified side bars S suitably braced at i), it being understood, however, that the form of frame and the means of securing the fabric there., are immaterial as they form no part of my present invention. The fabric, generally designated at l0, is secured in this frame at an end l2 in the end members 7. This fabric prefer-abitv consists of a plurality of rows of longitudinal orU-shaped links i3 arranged in rows extending.longitudinally of the fabric and a plurality 'of links il, whose form will be hereinafter described, arranged in rows extending transve; .ely of the fabric and connecting together the longitudinal rows and connecting also the adjacent links 13 of each longitudinal row. The U-shaped linksV 13 in the present instance consist of a single piece of wire bent to the form shown in Fig. 3 and have a pair of relatively long parallel legs if; bent at their ends to form hooks or eyes which are engaged, as willbe later described more in detail, with-the transversely arranged links 14. Each of the latter links coi 'sts alsovof a single piece of wire having a straight central portion l? and oppositely extending loops i8 and l5) at each end, the loop 1S which is the loop nearer the centri l portion being disposed in a horizontal plane whenthe fabric is assembled and the vloop 19 which is at the end of the link being in a vertical plane. f

ll'hcn the fabric is assembled the loops 1Q at the ends of the links 14 are engaged at the centers 20 of the longitudinal loops. the loops 19 of twoadjacent links ll of the saine row engaging each U-shaped link lil at'its center. the next adjacent U-shapcd link are. engaged in the two loops 1S of adjacent links 'les which are thus brought'together, as will be seen in Fig. l. Thus the links il connect the individual U-shaped links of each longitudinal row and with these U-sliaped links form a part of this row, so that when tir fabri-tl is secured in the frame by the lielica springs l1 the pull of these springs is fel not only by the U-shaped links of the longitudinal rows but by thc transversely.' disposed links 14: through the ends which con The hooks or eyes 1G at the ends of' nect the adjacent links 13 of each row. This holds all of the links in the fabric always under tension and prevents any independent movement of any of the links or other parts of the spring such as would produce rattling or other noise.

The loops 18 serve to maintain the legs of the U-shaped links in substantial parallelism so that`the pull on the fabric when the link is secured as sh'own in full lines in Fig. 1 is felt along substantially straight longitudinal lines as is desirable in this type of fabric and there is no part of this pull Ywhich Will tcml to distort any of the links forming the fabric. This permits the use 'of Wife Of rela# tively light weightv to form the imite .as there is no tendency for the links to separate or become distorted .in use. h

The edges of the fabric may be formed by the usual band 21, shown in Fig. 1, or it may be given what is generally termed a straight edge or wire edge, as shown in Fig. 5. l/Vhere a band is used it may be connected to the fabric by using the connecting members 22 each of which is substantially half of a link 14, thefree end of this mem# ber being bentfthrough, or otherwise fixed, in an eye 23 provided in the band. Where a straight wire edge is desired one leg 24 of the edge row of U-shaped links is made longer than the-other leg 25, which last-mentioned leg is aA substantial duplicate of one of the legs l5 of the link 13 earlier described.

The additional length of the leg 24 com.

pensates for the end of the adjacent link 14 which connects the leg 25 vwith the next ad.

jacent edge U-shaped link and the end'of the leg 24 is bentaround the center 26 of the next edge link, so "that the links at the edge of the fabricj are connected in part by an adjacent transversely disposed link 14 and in part by engagement of the leg 24: with the center of the next adjacent link. This provides a substantially straight edge.

Where either form of edge is used there is 'little tendency of the fabric to contract materiallyunder weight as the pull upon the longitudinal rows falls insubstantially' straight lines which are maintained at evenly spaced relations by the links 14. The

loops 18 prevent any slipping of the eyes 01j' hooks 16 and consequently prevent in large part any possible distortion of the fabric.

The fabric is connected to the helical springs 11. by merely hooking the helical springs through the centers 20 of the links at the end of the fabric at which the end?l with their cen-'Q tending longitudinally ofthe fabric, and a U-shaped links are disposed ters at the edge of the fabric, as seen at the left in Fig. 1, and hooking 'theYV springsat the other end through the two ends of each link, as seen at the right. The connection of the a plurality off connecting 4adjacent longitudinal rows of -links and connecting alsofadjacent links of 'thesame longitudinal row. l,

hooked ends of the links 13 to the l loops 18 of the transversely arranged links' 14 is substantially a pivotal one and when it Fig. 1, mayn be arranged midway between two longitudinal rows'and engagd atgthe centers of the end links,. as shown also in,

'- dotted lines. This may be repeated across the fabric and the helical springs thereby required reduced by one-half at this end of the spring and a similar arrangement may be resorted to attlie other end.

It will 'be ,apparent that the transverse 'links 14:., when constructed and Connected in the fabric as already described, provide suiiieient transverse yielding of the fabric and permit these links to move with 'a slight ivotal action as the fabric gives in use, so that there is no tendency to bend any of the units or links when weight is placed upon and removed from the spring. Where the transverse links'are rigidly connected so that they .may not give. in this manner they eventually crystallize and break.

It will be obvious that various changes -niay be made in the form and construction ofthe links without departing from the fabric, said last-mentioned links serving to' connect adjacent links ofthe saine row extending lengthwise ofthe fabric.
